hash::case::preserve

Hash::Case::Preserve(3pm)				User Contributed Perl Documentation				 Hash::Case::Preserve(3pm)

NAME

       Hash::Case::Preserve - hash with enforced lower cased keys

INHERITANCE

	Hash::Case::Preserve
	  is a Hash::Case
	  is a Tie::StdHash

SYNOPSIS

	use Hash::Case::Preserve;
	tie my(%cphash), 'Hash::Case::Preserve';
	$cphash{StraNGeKeY} = 3;
	print keys %cphash;	    # StraNGeKeY
	print $cphash{strangekey};  # 3
	print $cphash{STRANGEKEY};  # 3

DESCRIPTION

       Hash::Case::Preserve extends Hash::Case, which lets you play various trics with hash keys. This extension implements a fake hash which is
       case-insentive. The keys are administered in the casing as they were used: case-insensitive but case-preserving.

METHODS

   Constructors
       $obj->addHashData(HASH)
	   See "Constructors" in Hash::Case

       $obj->addPairs(PAIRS)
	   See "Constructors" in Hash::Case

       $obj->setHash(HASH)
	   See "Constructors" in Hash::Case

       tie(HASH, 'Hash::Case::Preserve', [VALUES,] OPTIONS)
	   Define HASH to be case insensitive, but case preserving.  The hash is initialized with the VALUES, specified as ref-array (passing a
	   list of key-value pairs) or ref-hash.

	   OPTIONS is a list of key/value pairs, which specify how the hash must handle preservation.  Current options:

	    -Option--Default
	     keep    'LAST'

	   keep => 'FIRST' | 'LAST'
	     Which casing is the preferred casing?  The FIRST appearance or the LAST.  Only stores will affect the casing, deletes will undo the
	     definition.  Defaults to LAST, which is slightly faster.
